[Development] QWebEngineView Print

[Sudhir Sharma]

Kevin,

Thanks very much for your response. Just upgrading QtWebEngine to 5.8 or 5.9 will suffice my requirement.
Exploring how can I do that as I have not built QT but using QT installer in Visual Studio 2013.

Do you have any idea if it can be done in my scenario?

Regards,
Sudhir

In 5.7, you can only print by first printing to PDF and then invoking something external to actually send the PDF to a printer. See the code (submitted by me) in QupZilla 2.1.x (and currently also in master/2.2, but since that requires Qt 5.8, it may be ported to the direct print method soon, I've been wanting to look into that for a while). But that code assumes the lpr executable is available on *nix, and there is an implementation for Windows that is rather suboptimal (invokes the configured PDF viewer and asks it to print).

You may want to upgrade to 5.8 or 5.9, where you just have to invoke the print method.

It is also possible to upgrade QtWebEngine to 5.8 or 5.9 while keeping Qt 5.7, you will just need this one-line fix:

http://pkgs.fedoraproject.org/cgit/rpms/qt5-qtwebengine.git/plain/qtwebengine-opensource-src-5.8.0-qt57.patch

and you may want to explicitly enable spellchecking, which is disabled by default when building against Qt 5.7:

WEBENGINE_CONFIG+=use_spellchecker

and if you are using CMake, you will likely also need this tweak on the installed QtWebEngineConfig*.cmake files:

sed -i -e "s|%{version} \${_Qt5WebEngine|%{_qt5_version} \${_Qt5WebEngine|" \
  %{buildroot}%{_qt5_libdir}/cmake/Qt5WebEngine*/Qt5WebEngine*Config.cmake

QtWebEngine is the only part that of Qt you need to upgrade to get the print method.
